Description

Foil exposure inspection control device and control method thereof

[0001] The present disclosure relates to a foil exposure inspection control device and a control method thereof. More specifically, the present disclosure relates to a control device for detecting a foil exposure area of ​​a battery cell and a control method thereof.

[0002] Battery cells, the core components of secondary batteries, consist of a cathode, anode, separator, and electrolyte. During the manufacturing process, the cathode and anode are each manufactured by coating active materials onto current collectors. Inappropriate exposure of the metal foil used as the current collectors for the cathode and anode during this process can lead to reduced battery performance or safety issues. Therefore, accurately inspecting for foil exposure during the battery cell manufacturing process is crucial for ensuring battery quality and safety.

[0003] Regarding conventional battery cell inspection technology, Korean Patent Application No. 10-2023-0008737 discloses a method for detecting electrode defects in secondary batteries. This technology focuses on performing image preprocessing (erosion and dilation operations) to remove electrodes and identifying the number of remaining electrodes.

[0004] These existing technologies have the following limitations. First, they primarily focus on image processing algorithms, lacking comprehensive user interfaces (UIs) and parameter setting capabilities required for the inspection process. Second, they focus solely on specific defect types (e.g., number of electrodes, edge lines), thus lacking the ability to comprehensively analyze various types of foil exposure (in / out) and measurements (e.g., width, height, short axis, long axis, angle). Third, existing technologies lack detailed functions for storing, managing, and visualizing inspection results, making it difficult to manage quality and ensure traceability in production settings. Fourth, existing technologies lack lot-level inspection history management and statistical capabilities, limiting quality control in mass production environments. Fifth, existing technologies lack detailed descriptions of inspection parameter setting and adjustment capabilities, making it difficult to perform optimized inspections for various battery types.

[0005] Therefore, a new foil exposure inspection control device is required that provides a comprehensive UI system for foil exposure inspection of battery cells, various parameter setting functions, lot-unit inspection result management and visualization functions, and various foil exposure type classification and precision measurement functions.

[0006] The embodiments disclosed in the present disclosure disclose a foil exposure inspection control device and a control method thereof that provide a comprehensive user interface (UI) capable of setting various parameters for foil exposure inspection or monitoring inspection results.

[0007] The problems to be solved by the present disclosure are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0008] A device according to the present disclosure for achieving the above-described technical task includes a display for displaying a UI; and a processor for performing a process for checking whether a foil is exposed through the UI; wherein the processor outputs a real-time image in which a tab area and a bottom area of ​​a battery cell are respectively captured, detects an exposed area in which a foil is exposed in the real-time image, determines the battery cell as good or defective based on the detection result, and generates and outputs an inspection result table matching the determination result to identification information of the battery cell.

[0009] Meanwhile, the processor can output a roll map that maps the locations of the battery cells within the lot and display the judgment results of the battery cells on the roll map.

[0010] Additionally, the processor can measure the inspection time for the battery cell and output a tact time graph.

[0011] In addition, the processor can extract the detected area from the real-time image and store it as a crop image, output a preset number of the stored crop images within a preset period of time, and display a serial number and defect information on the crop image.

[0012] In addition, when the exposure area is detected in the real-time image, the processor can identify the real-time image as one of the tab area and the bottom area, identify the foil exposure type as at least one of in and out based on the outer line of the tab, and determine the battery cell as good (OK) or defective (NG) based on the defective information.

[0013] In addition, the processor outputs the inspection result table that matches the judgment result, ink marking presence or absence, and inspection time for each identification information of the battery cell, and can output the color of each cell differently according to the judgment result.

[0014] In addition, the processor can load and output a teaching image, detect an exposed area where the foil is exposed in the teaching image, display defective information about the exposed area, and determine and display the teaching image as good or defective based on the detection result.

[0015] Additionally, the processor can set the recipe setting type to one of default, test, cathode, and anode, and set dimensional parameters, surface parameters, and foil specification parameters to save as a recipe.

[0016] Additionally, the processor can output the connection status of the camera and lighting controller for the real-time video capture, and output the real-time video to set lighting controller parameters and camera parameters.

[0017] In addition, a method for controlling a foil exposure inspection control device for inspecting whether a battery cell has exposed foil comprises the steps of: outputting a real-time image in which a tab area and a bottom area of ​​the battery cell are photographed respectively; detecting an exposure area in which the foil is exposed in the real-time image; determining the battery cell as good or defective based on the detection result; and generating and outputting an inspection result table in which the determination result is matched to identification information of the battery cell.
